You can use qtvcp's file dialog to just get the filename without loading the file by using a STATUS general message to call the dialog. In this way it manages size, placement extensions etc, but It wouldn't save the file name in the preference file or load the file into linuxcnc.

Obviously I wasn't subscribed to this topic since I just now saw your reply. Anyway, I currently have 2 buttons for loading files, one for gcode and one for html. They instantiate a QDialog and all works well. However, I will try the method you suggest and report back.

It does exactly what I am already doing but why does it report the contents of the dialog request 4 times? Can the filemanager widget be modified to not automatically load a selected file? This way, I could use it to just select a file and decide what to do with it based on the file extension.

I don;t know why it reports four time - if you still have the relevent files I would love to see.

I just pushed an update to file_manager so you can class patch the load(self, fname):
function to call a function in the handler file instead.
There is an example how to do this in the qtvcp code snippets section of the docs.

I haven't got the latest pushed update yet but I tried the class patching and it works. ( I didn't realize this is aka monkey patching )
Re: dialogs, every dialog that I call via
STAT.emit('dialog-request', mess)
or
ACTION.CALL_DIALOG(mess)
results in being reported 4 times in the console. You can probably only notice if linuxcnc is started from a terminal. This code is already in the example files.

yes monkey patching.

From memory that can happen if you have multiple instances of the same dialogs loaded.
I'm not sure what you mean by 'already in the example files' which example files?

If you didn't update then your patching will probably break when you update I changed the function signature - easy enough to fix it.

Sorry about the vagueness. To reproduce what I am seeing:
start linuxcnc in a terminal
select one of the configs under sim.qtvcp_screens.qtdragon
click on estop, power, home-all
click TOOL TOUCHOFF and wait for it to time out
There will be an error about timing out without making contact - expected
The contents of the dialog that was called will be displayed 4 times.
There's also something about Parameter file name is missing. - no idea what that is about.
Unrelated - there is an error about no attribute named proc but I have no interest in fixing that. I'm working on an updated version anyway.

Thanks.

In axis_tool_button widget, In the function 'return_message', there is a debug print statement that printed _all_ return messages (and of course each tool button would print it too).

I'll remove it and hopefully that will be that.

Hello Jim! Please tell me the mechanism of work of Probe Screen Widget.
Why the widget does not respond to probe-in. I see that everything is tied to a hal pin. I'm interested in how to connect to mesa 7i96. Thanks in advance!

I also use a 7i96 but I have the probe input run through a debounce component first. In qtdragon_postgui.hal file there is:

net probe-input debounce.0.3.in <= hm2_7i96.0.gpio.004.in
net debounce_p debounce.0.3.out => motion.probe-input

You could bypass the debounce and just enter:
net probe_input hm2_7i96.0.gpio.xxx.in => motion.probe-input

You can monitor the state of the hal pin in HALSHOW -> pins -> motion.probe-input. If it doesn't toggle with your physical probe input, then something is not connected right.
Also, the probe widget is inactive until the machine is ON and HOMED.
